Question

check for understanding: joint physiology

which type of joint allows for movements in all directions, essential for balance and power in bowling?

saddle joint
ball-and-socket joint
hinge joint
plane joint

Explanation:

Identify the key movement requirement

The question asks for a type of joint that allows for movements in all directions (multiaxial movement).

Evaluate the joint options

• Saddle joint: Allows biaxial movement (e.g., thumb).
• Ball-and-socket joint: Allows multiaxial movement in all directions (e.g., shoulder and hip), providing the widest range of motion.
• Hinge joint: Allows uniaxial movement (e.g., elbow and knee).
• Plane joint: Allows gliding movements (e.g., carpals).

Select the correct joint type

The ball-and-socket joint is the only option that allows movement in all directions, which is essential for the shoulder's role in bowling.

Answer:

• Saddle joint
• Ball-and-socket joint (Correct answer)
• Hinge joint
• Plane joint
